Abstract

A transparent, complex oxide ceramic having the formula:

What is claimed as new and intended to be secured by Letters Patent: 
     
       1. A transparent, single phase, complex oxide ceramic material of the formula (Sr 1-x  Ca x )(Li 1/4  Nb 3/4 )O 3  wherein x is 0.01-0.50. 
     
     
       2. A process for preparing a transparent, single phase, complex oxide ceramic material of the formula (Sr 1-x  Ca x )(Li 1/4  Nb 3/4 )O 3  wherein x is 0.01-0.50 comprising: blending the metal oxide components of transparent, complex oxide ceramic material with a binder;   shaping and pressing said blended materials under 0.5-2 ton/cm 2  ;   and sintering said shaped material under an atmosphere of oxygen at 1150°-1450° C. for 2-4 hours.
